Cloud computing accounting software is accounting software that is hosted on remote servers. It provides accounting capabilities to businesses in a fashion similar to the SaaS (Software as a Service) business model. Data is sent into "the cloud," where it is processed and returned to the user. All application functions are performed off-site, not on the user's desktop.

In cloud computing, users access software applications remotely through the Internet or other network via a cloud application service provider. Using cloud computing accounting software frees the business from having to install and maintain software on individual desktop computers. It also allows employees in remote or branch offices to access the same data and the same version of the software.

Most application providers typically charge based on usage – compared to site license fees associated with traditional accounting software deployments. Accounting data backup and disaster recovery is often a part of your cloud computing accounting software account.

Cloud computing accounting software may also be referred to as online accounting software or Web-based accounting software.
